Investors are interested in receiving the highest return on a portfolio, subject on some constraint in the risk involved. The Capital Asset Pricing Model (CAPM) is a linear model of the form: rs = α βrm ε, where rs, rm, are the returns of a particular security (s) and of the market as a whole...

We partially identify population treatment effects in observational data under sample selection, without the benefit of random treatment assignment. We provide bounds both for the average and the quantile population treatment effects, combining assumptions for the selected and the non-selected...

Interest in evaluating the effects of continuous treatments has been on the rise recently. To facilitate the estimation of causal effects in this setting, the present paper introduces entropy balancing for continuous treatments (EBCT) by extending the original entropy balancing methodology of...
